narrator · The primary narrator is Robert Walton, who, in his
letters, quotes Victor Frankenstein’s first-person narrative at
length; Victor, in turn, quotes the monster’s first-person narrative;
in addition, the lesser characters Elizabeth Lavenza and
Alphonse Frankenstein narrate parts of the story through their letters
to Victor.

climax · The murder of Elizabeth Lavenza on the night of her
wedding to Victor Frankenstein in Chapter 23

point of view · The point of view shifts with the narration, from Robert
Walton to Victor Frankenstein to Frankenstein’s monster, then back
to Walton, with a few digressions in the form of letters from Elizabeth
Lavenza and Alphonse Frankenstein.

falling action · After the murder of Elizabeth Lavenza, when Victor Frankenstein
chases the monster to the northern ice, is rescued by Robert Walton,
narrates his story, and dies

tense · Past

foreshadowing · Ubiquitous—throughout his narrative, Victor uses words
such as “fate” and “omen” to hint at the tragedy that has befallen him;
additionally, he occasionally pauses in his recounting to collect
himself in the face of frightening memories.

The book doesn't specify if the monster was created by one man or several or how he was brought to life. I think we can safely guess that the monster was brought to life using electricity because it has such an influence on Victor. SPOILER ALERT. I would also say that is safe to say that the monster was probably created using more than one man because later on Victor tears apart/destroys the monster's companion before he completes her creation. These are just my thoughts and if anyone has anything else they would like to add please comment
